Here's the AOS culture sheet. Although it's only useful if you know what type of Lycaste you have...

Lycaste brevispatha note the spelling is a fully deciduous pink species.

Phil's Orchid World has good info on the genus, sections, species and culture, but the navigation is quite klunky and it's easy to miss stuff. So I'll just list the individual links. Note that this is a New Zealand site, so flip the months if it gets into winter vs. summer season!

I can't find what section mattogrossensis note the spelling belongs to, but I've PM'ed Pat Mahon. He's up on Central American species, so I'm figuring he'll know.

I'm including the discussion on these sections, because they've some great reference info:

And general culture for the genus, beyond the specific needs of each section. Lots of good info in this!
